PORTABLE VULCANIZING APPARATUS.

Patented Dec. 22, 1908.

Application filed October 12, 1907. Serial No. 397,158.

To all whom it may concern:

Be it known that I, MAX SCHIELE, a subect of the Emperor of Germany, residing at Hanover, Empire of Germany, have invented certain new and useful Improvements in Portable Vulcanizing Apparatus, of which the following is a description, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon.

The principal object of the present invention is to provide a small portable vulcanizer of such size that it may be readily carried by automobilists, and employed in repairing punctures in either the inner or outer` tires, thus avoiding the expense and delay which follow accidents occurring at points remote from repair shops.

A further object of the invention is to provide a vulcanizer which can be practically used to make permanent repairs by any person and without the necessity of exercising any special mechanical skill.

A still further object of the invention, is to provide a device which may be used to repair outer tires in situ, without the necessity of removing the tire from the wheel.

A still further obj ect of the invention is to provide a vulcanizer in which provision is made for rapidly generating steam and superheating the same before it passes to the vulcanizer box or casing.

In the accompanying drawings which illustrate my invention, Figure 1 is a vertical section of a portable vulcanizer constructed in accordance with the invention Fig. 2 is a view of a portion of the same, as used in repairing an inner tube and Fig. 3 is an end view showing the lamp-attaching device.

Similar numerals throughout the drawings and specifications, refer to corresponding parts.

In carrying out the invention, a box or casing 10 is formed, preferably of stamped sheet steel, and the joints are brazed to form a strong steam-tight casing. The bottom 11 of the casing is concave, following approximately the contour in cross section of the tread orouter tube of a tire, so that it may be snugly fitted to the latter in case of puncture. At one end of the casing is a link 15 to which is hung a strap 16, which may be passed under the Wheel felly, and then through a buckle or clip 17 at the opposite end of the casing to repair a tire in situ. The

top 18 of the casing is shown as flat, although it may be slightly curved, and the end portions of the top are extended beyond the vertical walls of the casing, to form bolting flanges 19, having openings for the passage of a number of bolts 20.

Above the top is arranged a detachable clamp plate 2l, also having openings for the passage of the bolts 20, and this plate may be removed to permit the placing of an inner tube on the top 18, after which the clamp plate is bolted down, in order to hold the tube against the heated surface during the vulcanizing op eration. Y

Arranged at one side of the casing is a small boiler or steam generator 25, which' is supported by a tube 2G, that extends from the boiler to the casing, and has a contracted discharge end 27 in communication with said casing. This tube forms a steam superheater to which steam is supplied from the boiler through a pipe 29, the upper end of which opens into the steam space of the boiler.

Suspended below the boiler is a heater 30, which in the present instance is in the form of a small alcohol lamp, having five burners, four of which, 31, are directed against the convex bottom of the boiler, while the fifth burner 32 is arranged to direct a heating flame against the superheater, so that the wet steam from the boiler will be dried, and its temperature increased before it passes into the vulcanizer box or casing. Y

The lamp is suspended by a pair of flat hooks 34, which are pivoted at their up er ends to lugs on the side of the boiler, the lower inturned ends of the hooks engaging in recesses formed in the sides of the lamp.

In order to protect the flame in case of high wind, an adjustable casing or shield 36 is employed, the shield being vertically slidable on the lamp body to any desired height, and serving also as a means for holding the lower ends of the hooks in engagement with the lamp.

At the top of the boiler is a safety valve 40, and connected to the vulcaniZer box or casing is a manometer 41. The vulcanizer is quite small and compact, and may be readily carried in an automobile. When repairs are to be made in a punctured outer tube or sheath, the wheel is turned until the damaged part is uppermost, after which rubber paste or compound or a soft rubber patch is placed over the puncture. The vulcaniZer is then fastened in place by running the strap 16 under the felly, and fastening its end to buckle 17.

The boiler having been supplied with water, the lamp is ignited, and as the steam forms, it asses into the super heater, where it is driecl) and its temperature raised, before passing into the vulcanizer box or casing. In case of excess of steam, one or more of the burners may be extinguished. The vulcanizer is allowed to remain in place for fifteen minutes, more or less, and the operation is complete. After the removal of the vulcanizer and extinguishing the lamp, the steam condenses and may be run back into the boiler to be reused, if necessary.

When repairs are to be made to an inner tube, the paste, compound or patch, is applied, and the tube is clamped between the top 18 and the plate 21.

If desired, the surfaces of the box which are not in use for vulcanizing purposes, may be covered by heat insulating material, such as asbestos or the like.

It will be noted that the device requires no permanent stand, base-or frame, and for nearly all repairs, the majority being to outer tires, the vulcanizer is supported by the wheel of the vehicle. The apparatus may vbe packed in a small box for transportation.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

l. In a portable vulcanizer, a box with means for attaching to a wheel for repairs in situ, a boiler, a steam tube leading directly from the boiler into the box, and means for directing heating llames against the boiler and tube, whereby the steam passing through the latter is superheated.

2. In a portableA vulcanizer, a box, a boiler, a tube connecting the box and boiler,

said tube supporting the vboiler and means for directing heating llames against the boiler and tube.

3. In a portable vulcanizer, a box, a boiler, a superheating tube forming a direct connection between the box and boiler, and supporting said boiler, a steam pipe leading from the steam space of the boiler to said tube, and means for directing heating flames against the boiler and tube.

4. In a portable vulcanizer, a box, a boiler, a tube connecting the shell of the boiler to the box and having a contracted discharge into the latter, a steam pi e leading from the steam space of the boi er into said tube, and means for directing heating flames against the boiler and tube.

5. In a portable vulcanizer, a vulcanizer box, a boiler, a su erheater connecting the boiler and box, an a lamp suspended below the boiler and arranged to heat the boiler and the superheater.

6. In a portable vulcanizer, a vulcanizer box, a boiler, a superheater connecting the boiler and box, and a lamp suspended from the boiler and provided with a burner under the superheater, and a burner under the boiler.

7. In a portable vulcanizer, a vulcanizer box, a boiler connected thereto, a lamp body having side recesses, hooks carried by the boiler, and having inturned ends arranged to enter said recesses, and a lamp shield acting also to hold the hooks in their recesses.

8. In a portable vulcanizer, a vulcanizer box, a boiler, a steam tube between the boiler and casing, and a heating lamp having a plurality of burners directed against the boiler and tube.

In testimony whereof I aflix my signature, in presence of two witnesses.

MAX SCHIELE.
